PAMP-pathogen -associated molecular patterns: a. Enable lymphocytes to recognize microbes and disrupt them b. Are cystein-rich peptides of leucocytes c. Are recognized by PRR -receptors of innate immunity d. Are proteins on the surface of infected cell

The correct answer is:<br /><br />c. Are recognized by PRR -receptors of innate immunity<br /><br />PAMPs (pathogen-associated molecular patterns) are molecular structures that are associated with groups of pathogens and are recognized by the innate immune system. They are typically found on the surface of microbes and are recognized by pattern recognition receptors (PRRs) on cells of the innate immune system, such as macrophages and dendritic cells. This recognition triggers an immune response to eliminate the pathogen.
